Abstract: The invention relates to an automatic concrete pump with an articulated mast (14) serving as a support for a supply line and with two forward and two backward support extensions (16?,16?,18?,18?) which can be supported on a base platform (32) and which can be lowered from a driving position into a support position, each with a telescopic support leg (30). According to the invention, each support extension comprises one inner support position near to the chassis, and at least one outer support position away from the chassis, which can be freely selected by forming defined support configurations (V,SL,SR,YL,YR,N) for the four support extensions.

Abstract: A mobile implement, particularly an automatic concrete pump, with stability monitoring system includes an undercarriage supportable on a subsurface by two front and two rear outriggers. A respective measuring element is disposed in the telescoping support legs of the outriggers for determining the supporting force. Each support leg has an upper telescoping element connected to the associated outrigger at an upper connection point, and a support base displaceable relative to the upper element and supported on the subsurface at the lower end thereof at a lower connection point. The measuring element is disposed either directly at the upper connection point between the outrigger and the upper telescoping element, or in the region of the lower connection point between the lower telescoping element and the support base.

Abstract: The invention relates to a material feed receptacle for a thick matter pump comprising a receptacle lower part and a receptacle top that is detachably connected to the receptacle lower part, a two-part front wall, a rear wall, two two-part lateral walls, an upwardly pointing material feed opening delimited by a peripheral edge, and a pipe junction, which is situated inside the receptacle, can, on the entry side, swivel in an alternating manner in front of the delivery cylinder openings and which, on the output side, leads to a pressure pipe. The invention provides that the receptacle top has an upper lateral wall part and upper lateral wall parts, which have free ends and which extend away from the front wall part. The invention also provides that the peripheral edge has a first edge part, which forms an upper edge of the receptacle top, and ha a second edge part on the receptacle lower part, which is situated on the rear wall and is joined to the first edge part.

Abstract: The invention relates to an end hose for discharge of thick substances, particularly of liquid concrete. The end hose (12) can be connected with its entry-side end to a pressure feed line (14) of a mobile thick-matter pump, and has a discharge opening (16) for the thick substances at its exit-side end, and consists of a flexible material. In order to prevent the end hose (12) from kicking out when blockages are loosened, it has at least two hose parts (26, 28) having different bending rigidity, connected with one another at a transition point (30).
